Hi Andrew,
Today's linux-next merge of the scsi-post-merge tree got conflicts in
arch/x86/kernel/apic/apic.c, arch/x86/kernel/cpu/mcheck/therm_throt.c,
arch/x86/kernel/cpu/mcheck/threshold.c and arch/x86/kernel/irq.c between
commit ef14aea88fee ("x86: Call idle notifier after irq_enter()") from
the rcu tree and commit 6a541324a31f ("The current interrupt traces from
irq_handler_entry and irq_handler_exit") from the akpm tree.
Just context changes. I fixed them up (see below) and can carry the fixes
as necessary.
